| 摘 要： | 物源分析是确定盆地演化的重要条件之一,物源成分变化反映盆山耦合关系。砂岩骨架矿物成分变化反映沉积物源区的构造属性及其变化。通过对三穗地区青白口系隆里组的砂岩系统采样,进行了详细的鉴定,观察砂岩的碎屑组分与结构的变化特征,同时还应用Dickinson的分析理论对其进行了砂岩骨架矿物统计分析。结果表明,隆里组砂岩具有混合物源,由大陆块物源区和火山弧物源区共同提供。

| Abstract: | Source analysis is an important condition for basin evolution determination, the source material change reflects the coupling relation of basin and mountain. The matrix mineral change of sandstone reflects the structural feature and its changes of sediment source area. By sampling and detailed survey the sandstone system of Longli formation in Qingkoubai series in Sansui area, the clastic component and structural changes of sandstone are observed, meanwhile the matrix mineral of sandstone are counted and studied by the analytical theory of Dickinson. The results show the sandstone in Longli formation has mixed source which include continent and volcanic arc. |
